factory in the shortest possible time. It is your responsibility to ensure that the goods have arrived in

perfect condition. Failure to indicate the damage and the absence of communication of the same

invalidate any claim. In the event that the product conforms to thereafter transport and maintenance

is your responsibility.

If units are going to remain stored until placement need to verify that they are located in a clean, dry

place. Avoid leaving the equipment packaged with protective film to the sun for long. The direct

sunlight over a period of prolonged exposure on the protective film may deteriorate paint equipment.

Check that all panels and the electrical panel are closed. Check inside remains protected circuits.

The units may be accompanied by matching structure or curb for placement. In the event that it is

included in the order, check the adjustment curb meets the specifications. If a rooftop curbe for

special adaptation to a pre-existing installation is going to be used, prior to manufacture the

customer approval is required to a drawing prepared by the technical office of Nortek Global HVAC, to

verify that the design meets the curbs need for installation. It is your responsibility to ensure that the

curb corresponds to the design shown in the drawings when material has arrived on site

INSTALLATION AND SET-UP

The final location of the unit will determine largely the proper functioning of equipment. For the best

performance use the following guidelines:

Upon receiving your unit, please inspect your machine and its components for damage during

shipping. Install the unit outdoors and away from heat sources. Before to install the equipment it is

important to check that the selected surface has sufficient strength to support the weight of the

15

machine, vibrations and effort that it can transmit. Ensuring the integrity and security of the

installation.

Do not obstruct air inlet or outlet spaces of the unit to facilitate the air intake and exhaust flow and

avoid as far as possible recirculation of air into the unit.

To ensure proper operation of the equipment and allow access for maintenance, respect the

minimum distances recommended.

Install in their location on type silentblock shock absorbers

Make sure the electric panel is in good condition before making the electrical connection, and please

follow the guidelines:

Follow the wiring diagram provided by the manufacturer.

Note that models to 400V/III/50Hz have a supply connection to 5 wires, being always the grounding

in colour green-yelow.

Install appropriate protective device on the undertaken line, thermomagnetic or thermomagnetic

differential. In cases where it is installed more than a machine it must be provided of its own system

of protection to each line.

To calculate the section of wires of the supply connection it should be considered electrical data

provided in the unit´s nameplate and other factors such as the length of the supply connection, the

type of wiring used, etc.; always respecting current regulations for electrical installations.

START-UP

INSTALLATION AND COMMISSIONING

The air conditioning units are autonomous Reznor RTU compact air conditioning units. The following

diagrams indicate the outer dimensions of the equipment:

The final location of the unit will determine largely the proper functioning of equipment. Install the

condensing unit outdoors or a place with good air exchange and away from heat sources.

For installation of the equipment will be necessary to check that

the selected surface has sufficient strength to support its weight

and vibrations and efforts that can transmit, ensuring the integrity

and security of the facility.

Minimum distances for commissioning and maintenance

It is necessary to maintain the minimum clearances for maintenance and security. Clear the air intake

areas of the unit for easy intake and exhaust air, and avoid as far as possible the recirculation of air

into the unit.

To ensure reliable operation of the equipment and allow access for

maintenance, observe the minimum distances recommended.

In the case of installing multiple units next, avoid installing units too

close, so that it can restrict airflow to the condenser. Not respecting the

minimum distances can lead to malfunction of the unit.

Please check minimal distances drawings

In the case of installing indoor units it is necessary to pay attention to

the prevailing wind in the area. In areas of excessive wind you need to

check the placement of the registers and dampers covering parts, and

that they do their task properly

Before installing the equipment, make sure that they are to be installed on a clean surface free of

obstacles. Avoid non-horizontal surfaces.

When installing the equipment on the rooftop deck or on the bed, check that all lines are connected

correctly to take the unit, and properly seal ducts and intakes to prevent any air leakage during

operation of the unit.

For bench mounting adaptation, ensure that the unit is correctly placed over the curb and the

tightness of the whole rooftop unit and bench remains after assembly. A bad installation can lead to

air leaks. In some areas, a bad installation can mean that the rules of local regulations heating systems

32

and fire protection are not met. The assembly of the rooftop unit and the curb is responsibility of the

customer.

Electrical installation

Check that the electrical installation of the work to local regulations

apply. Do not connect the units to provisional light work. The units must

be connected up in the final wiring. Check that the section of the wires

complies with current regulations under the conditions of operation. If

the unit is three-phase with neutral and ground, verify that the

installation is equipped with three-phase network with neutral and

ground. The unit must be connected to the network correctly. Otherwise

it may not make the launch.

Make sure that all connections are properly made machine before

putting the unit on. Check with the wiring diagram that all components

are properly seated and connected, especially the security features, such

as circuit breakers and the main switch.

To start the unit, check that all circuit breakers are open, and turn the

main switch. To start the unit you must have a thermostat control unit or

connect the remote maintenance CLIMANAGER regulation.

After opening the general cut-off switch if the contactor coils are turned all the elements will start.

Check the direction of rotation of the elements. Compressors and fan motors are equipped in header

with a phase control relay. The (standard) Basic model has only phase failure and direction of rotation.

The sophisticated model (optional) also detects phase unbalance, undervoltage and overvoltage. If all

parameters are correct, the compressors will properly rotate.

A compressor runs backwards makes an abnormal noise. The

compressor will turn upside down for a while until it fails completely.

Avoid rotating compressors backwards long

If any of the elements counter-rotating to the right, cut off the main supply voltage bycutting off the

main switch and reverse the two phases, until all elements rotate in right direction.

33

CLEARANCES

Clearances must be respected according to below drawing. The safety distance must be respected in

order to access maintenance or replacement of items in case you need to install spare parts.

35

VENTILATION

Once it has been verified that all elements revolve right direction, connecting the gauges to measure

pressure and start the computers in cooling mode. Check readings of the manometers. The value of

the readings depend on weather conditions.

It must be checked the operation of all elements of the ventilation system. If the computer is

equipped with belt drive and pulleys, ensure correct installation of these elements. It is necessary to

check the operation of the dirty filter pressure switch, pressure switch air flow sensing probes, when

the units carry these items. Disconnect the circuit breakers of the fans and blowing units, and check

the high pressure reading gauges must be verified.

If the equipment is mounted with radial fans with electronic EC motors, it should be connected to the

computer with the right software and the set-point of the fan flow should be introduced into the

system.

Centrifugal fans are made of galvanized steel. EC radial fans can be of high strength polymers or

aluminum, depending on sizes.

The fans are suitable for outdoor air transport, free of particulate or corrosive vapors and gases. For

high humidity or excessive closeness to the sea should be consulted installing epoxy painted fans.

The fans are all mechanically balanced at the factory. When replacing a fan and

have to be transported and elevated, take special care to use separators chains

or slings to avoid damage to the fan.

The operating temperature limits of centrifugal fans are -20 ... + 45 ° C.

43

Centrifugal fan units with belts and pulleys

For equipment with motor driven centrifugal fans with coupling pulleys and belts, is necessary to

check at receiving equipment the belts are positioned correctly and stressed. All equipment is tested

at the factory, so that the belts have operated for testing at least 10 hours. However during transport

they may slacken. Is necessary to check the belt tension, the axle alignment and positioning of the

boss or tappers. Normally if the belts are not positioned correctly produce abnormal noise.

To tighten the belts, using the motor mount screw. To measure

the belt tension can be used the method of force - deflection.

Applying a force perpendicular to the belt, you should check that

the recommended deflection is 15.7 mm per meter from center to

center.

The belts must be replaced when they fail to properly stress or when show visible damage. Excessively

loose belt can slide and this generates heat and may result in premature deterioration of the strap

and its ruling. On the other hand if the belts are too tight, it can cause failure of the same or becomes

excessively suffer bearings fans and motors, which can in turn fail. Typically fails fan shaft bearing.

The most appropriate method to control and measure the tension is to use a suitable gauge, usually

supplied by the suppliers of belts. There are also electronic meters that are more accurate. In case you

need to change the belts for wear and tear over time, it is always recommended to check the original

specification and use original belts or the same quality as the original. Poor selection of the belt can

lead to a serious failure of other components such as the fan or motor.

Pulleys

The fans are equipped with bearings designed with a rated average life 40,000 hours of operation.

(L10 according to ISO 281-1), provided they do not exceed the load limit. Not to exceed the limit load

is recommended not to install smaller diameter pulleys to the minimum diameter. Minimum pulley

diameters are applicable provided that the straps are tensioned according to specifications. Excessive

belt tension can lead to premature deterioration of bearings or even fan shaft breakage.

The following table shows the minimum diameters of the pulleys to be installed in the AT fans voltage

conditions suitable belts, depending on engine power. The maximum recommended number of belts

is two. Only under certain conditions it supports up to three belts.

44

To proceed to change pulleys, unscrew the screws (3), tighten the Allen head screw (4), press the hub

and remove the pulley.

To proceed to fix the pulley, pull the pulley and the hub and place the allen head screw (3) connecting

the two parts. Align the motor pulley and the fan, exactar way, using an aligner, and place and tension

the belt according to instructions.

Axles and bearings

The fan shafts are made of carbon steel C40. The axes are equipped with a

keyway. The axes are protected against corrosion. The bearings are maintenance-

free, and use grease lubrication high performance and high durability. In case of

continuous use at high temperatures or has exceeded the hours of operation, can

be relubricated using recommended fat

For the purpose of calculating the transmission must be added losses of standard features, indoor

coil, indoor air channel, the losses of the corresponding filters of the unit, and the available pressure.

The sum of these values gives the total static pressure for selection of the fan.

49

If the airflow is not the nominal value, it must be corrected by a factor equal to the ratio of the flow

squared. With the value of the pressure and flow rate, it is entered in the chart of the fan, and

electrical power consumption and speed of the fan is obtained. The motors are fitted as standard IE2

high efficiency, so that the value of the power required to be increased inversely with the engine

efficiency. The engine speed is used to select transmission. The ratio of the diameter of the smallest

and largest pulley must be equal to the ratio between the recommended regimen of graphic rotation

and the rate of nominal rotation of the electric motor. Conventional engines used on rooftops, unless

specific constructs are four poles. You should always check that the size of the pulleys are eligible for

motor shafts and fan to avoid mechanical failure.

In any case, it is recommended to consult Reznor technical department with plant data for selecting

items that best suits the particular application.

In special applications are available centrifugal fans with backward curved blades or reaction, for

working with higher pressures available than standard fans action.

Ventilation options for the condensing unit of rooftops we contemplate the option of High Energy

Efficiency with axial fans with EC technology and electronic control of condensation (High Energy

Efficiency), Low Sound, enhanced axial and radial centrifugal fans with available pressure for indoor

installation with ducted air condensation, all available with AC or EC motors. Units are prepared in

standard with condensate tray in the outdoor unit for indoor installation technical rooms.

51

Axitop is a diffuser which is placed directly over the fence of axial fans diameters 800 and

910, and that reduces the noise level of acoustic pressure directly up to 7.2 dB (A). It can also

be used to enhance the fan, giving a 9% performance.

Before beginning assembly, make sure the engine model corresponds to the model supplied AXITOP. Several types of AXITOP depending on the engine and the diameter of the nozzle. To do so check the label (see diagram above). Check that you have the support rings (A) and the terminal box (E).

Example

52

Position the fan with the support ring, making sure the press screwed into the final assembly position

pointing downward (this only applies to vertical mounting). Insert and tighten the screws. Then

proceed to the connection of the terminal box, being careful to follow the same order of wiring was

observed when removing the connection. In the case of engines 150 (of size 910 fans), install the

cooling tube (see picture)

Finally, mounting the diffuser as shown in Fig. If the diffuser is removed, it must be mounted to be

placed on the fan.

Assembly and filter replacement

The access panel of the indoor unit provides access to maintenance of filters and motorized

dampers. The graph on the left shows the position of the main elements of the indoor unit

mounted active recovery.

The image shows a unit with EC radial fans in drive, mounting free cooling and three registers, and

return centrifugal fan mounted filters before the coil. The photo on the right shows a detail of the F7

compact filters in its rails. The rail allows the extraction of the filters easily for replacement and

cleaning. The rails are removable and are completely painted with epoxy-polyester paint thermally

oven-cured.

Standard equipment incorporate a pre-filtration stage and up to two stages of filtration. The filters are

mounted in a self-supporting structure made of galvanized sheet steel painted with epoxy-polyester

paint oven cured, removable rating and air leakage L2 according to the EN1886 standard.

Optionally, depending on the type of installation, the equipment can also manufacture:

- Only the prefiltration step

- With the prefiltration step and a filtration step

The pre-filtration stage can be set from the following types.

- Prefilter very low pressure drop, washable 15 mm thick.

- Prefilter efficiency G2, G3 or G4 extractable metallic rail painted galvanized steel 25 mm wide,

cleanable.

The electronic control allows EC radial fans by keeping the air flow, which will regulate according to

the fouling of filters.

55

Hot water coils for heating

The hot water coil is an optional recommended in applications where the outdoor temperature drops

below 5 ° C a high number of hours during the year. The backup coil is a tube and fins heat exchanger

for hot water with two rows. The hydraulic connections are located inside the supply air module.

The backup coil optionally assembles hot water valve three-way on / off or proportional valve

actuator.

The use of glycol for freeze protection for all applications is recommended. In low temperature

conditions the use of glycol is mandatory, as it is the only protection against freezing. When the

installation is left unused for a long time, you should check that the facility is clean, drained and

empty water. It is important to remember that the mixture of monoethylene in the presence of air can

cause corrosive agents. Check that the circuit has drain valves at a low point to allow emptying of the

installation.

It should be checked that the hydraulic system has traps in the highest point of the pipe to allow the

purging of air.

Use glycol to protect the coil from freezing. The warranty does not

cover damage caused by freezing the coil.

Electric heaters for heating

Electric coils are built to support independent modules which are mounted on brackets inside the unit

module, next to the cooling coil.

Electric coils are formed by modules of finned steel tube 1, 2 and 3 kW. The resistors feature a

thermistor high temperature safety.

versa.

Management by remote control and kind of probes supported

The board is prepared to support remote control type THT, as well as inputs for external signals of

Start /Stop, Cooling/Heating mode and an alarm output from the machine.

The following list contains each of the active/passive probes for which the board’s hardware and

firmware alike are prepared:

Analog sensors

- NTC probes: passive analog input (resistive).

(AIR/AIR: pumped, return, mix and exterior air in addition to extra-pumping in the event of

gas burner).

- Freon pressure transducers: analog input 0-1VDC. / 0-5VDC.

- Air pressure transducers: analog input 0-1VDC. / 0-5VDC.

- Interior/exterior temperature and/or humidity probes: 4-20 mA / 0-1VDC/ passive resistive /

RS485 Modbus or Carel.

- CO2 sensors: 0-1VDC / 4-20 mA.

79

- Air quality sensors VOC: 0-1VDC / 4-20 mA

- Combined sensors VOC+CO2: 0-1VDC / 4-20 mA

Digital sensors

- High pressure switch: digital input.

- Low pressure switch: digital input.

Through the Field-Bus card, the communication with probes and with other enabled equipment is

allowed by RS485 transmission and MODBUS protocol.

- Other CLIMANAGER cards

- Temperature and/or Humidity probes.

- Network analyser (energy analyser)

- EBM electronic fans

- Gate servomotors.

- Driver modules for Electronic Expansion Valves

- Driver modules for Inverter Compressors

- Driver modules for Digital-Scroll Compressors

The pLAN card allows the connection with PDG1 / remote PLD PRO and with other CLIMANAGER

cards.

The board is prepared without any optional equipment (no more than TCONN card) to be remotely

connected to other machines or devices (15 units maximum) by means of a PGD1 remote control.

Fan management

CLIMANAGER platform allows the connection of EC technology electronic fans, two External Unit

circuits, Pumping and Return.

80

- Control through 0-10V signal or PWM without driver or additional module.

- Digital input so that the fan communicates state or alarm.

- Likewise the board allows conmmunication with these equipment through RS-485 in the

event of setting up these fans in a network.

CLIMANAGER platform allows a double Star-Triangle output for the External Unit fans.

The Return and Extraction Fans are simultaneously incompatible, these fans can be Centrifugal, Radial

or Plug-Fan, using analogic or digital outputs.

The extraction fan operates according to the following functioning logic:

- Mixing Gate Completely Closed (0%): speed 100%

(ON in the case of ALL/NOTHING)

- Mixing Gate at 30%: speed 70%

(ON in the case of ALL/NOTHING)

- Mixing Gate at 50% and higher opening: speed 0%

(OFF in the case of ALL/NOTHING)

Electronic Expansion Valve Management

The board enables the control of the electronic expansion valve driver by means of FieldBus

(RS458@MODBUS). For that purpose universal drivers are used to work with electronic valves.

Gate Management

The board enables the control of 0-10 VDC or ON/OFF proportional Servomotors for gates. In the

same way, the board allows conmmunication with these equipment through RS-485 in the event of

setting up these fans in a network.

The 3 gates are controlled by means of 2 signals.

External and Exhaust Air: simultaneous functioning

Mixed Air: with an independent signal from the previous ones, this gate will be 90º out of

phase in relation to such signals with a parametrizable differential depending on the

installation specific needs.

Compressor Management

The board allows the control of the following compressors without an external driver.

ON / OFF

Digital-Scroll Copeland: based on Triac and suitable for the Active + recovery option

Inverter: DC and AC versions

The maxiun number of compressors managed is four in two main circuits +2 of the recovery circuit.

Support accesories management and other options

CLIMANAGER platform allows the communication with a network analyser per machine through

Fieldbus, showing consumption, intensity and cosPhi on screen. Consumption lever alarms may be

enabled.

The platform can control a 0-10VDC three ways proportional valve unit for Hot Water Back-up Battery,

and can control pumping back-up or anti-icing resistances, in two stages on/off. It counts on firmware

and outputs for at least one humidifier type ON/OFF, 0-10Vdc or FieldBus.

81

It has an output for a one-or-two-stage gas burner unit.

To that end it must have enabled: gas burner alarm signal input, burner discharge probe connection

and ON / OFF output for the two burner stages.
